🔐 VaultCrypt — Zero Knowledge Distributed Storage

Live · GitHub

• distributed storage layer pooling multiple cloud providers (e.g. gdrive accounts)
• zero-knowledge design → server never stores keys, seed, or chunk map
• file sharding via ChaCha20-DRBG obfuscation across multiple chunking strategies
• secure token storage using AES-256-GCM encryption at rest
• handles 1000+ concurrent operations with sub-500ms latency

🧠 GitScope — Codebase Intelligence Engine

Live · GitHub

• converts any repo into a readable narrative
• AST-based parsing using Tree-sitter for function-level understanding
• LLM-powered summaries + commit evolution stories
• semantic search over 50k+ LOC using ChromaDB
• reduces onboarding time by ~60%

⚙️ Beagle Tester Extensions (GSoC 2025)

• extended hardware testing framework in C/C++
• mikroBUS Click auto-detection (I2C scan + EEPROM parsing)
• added HDMI validation, web dashboard, MQTT publishing, CI pipeline
• ~30% performance improvement
